Numerical modeling and analysis of self-powered synchronous switching circuit for the study of transient charging behavior of a vibration energy harvester
Bibliographic record
Abstract
Abstract Enhancement of power harvesting efficiency in piezoelectric energy harvesters through a non-linear electronic interfacing circuit is a well-established research area with potentially significant implications on piezoelectric energy harvesting efficiency. Among various types of synchronous switching circuits available in the literature, a self-powered electronic breaker is widely studied. Nonetheless, due to the interdisciplinary nature of this field, many of the currently available analyses tend to overlook and/or simplify certain aspects of this dynamical system. As a result, a comprehensive model of the system that considers accurate coupling effect of the interfacing and storage circuitry, as well as detailed analysis of the system during transient capacitor charging and energy harvesting operation is still missing. This paper thus aims at the problem of modeling a piezoelectric energy harvester with an Synchronized Switch Harvesting on Inductor (SSHI) circuit and a self-powered electronic breaker. A semi-analytic numerical model is proposed that is able to accurately simulate the operation of the system during transient process of charging an external storage device. Experiment validation confirms the accuracy of the proposed model considering the exact electromechanical coupling effect and transient charging dynamics with SSHI circuit and the model’s performance in estimating system transient behavior. Furthermore, a systematic parametric study is performed in order to analyze the effects of different system components on the energy harvesting efficiency during transient operation.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
